-They are definitely filming at the airport for the premiere, so it appears that at least part of the episode will pick up right from the finale. Credit: anonymous

-Scenes will be filmed at a chapel with a lesbian couple, a tattooed couple, and a redneck couple. Credit: Taylor

- I don't believe there was any dialogue in that scene. Lucas just sees Peyton through the crowd, and vice versa, then they like run to each other and start makin out every which way lol then towards the end of the scene, he puts his hand on the back of her head and she does the same. credit: nbetterbid @ OTHforums

-LP share a spinny kiss at the airport. credit: Taylor

-Hil and Chad filmed two scenes, the one in the airport with the same clothes they wore in the finale. And a second one that took place in a car (a rental car), Hil wore the white dress and Chad had on a navy suit...which is what he is wearing in the pic w/ me. Thats all I know. credit: Taylor

-Gus is the card dealer and towards the end of the dream, he tells Lucas something like, "You can only make one choice." Then when Lucas wakes up, and he sees Peyton walking towards him, Gus who's now a passenger at the airport, looks up and says to Luke, "Looks like you made the right choice."

-This is the dialogue with LP at the airport that was told to me by a few people. It may not be perfectly accurate but it's pretty close....

Peyton: You do not just ask someone to marry them over the phone.
Lucas: then why did you come? (kissing)
Peyton: Because you're a mess, Lucas Scott, but you're my mess and I love you.
Lucas: I love you too.
(kissing)

-Brooke gets a text- from Peyton. And Haley gets one from Lucas at the same time- same words. They end the scene assuming that LP are together but not know what they're doing since basically the text just says "Don't Worry I'm okay"

They text first. Brooke says to Haley I haven't heard from Peyton and she didn't come home last night I wonder if I should be worried?" and at that moment she gets the text.
After the BH scene theres an LP one in the hotel in Vegas and it explains why they sent the texts.

There's a scene on an airplane and they may talk about things there. But I don't remember the dialogue.
Other than that they only talk about the task at hand. Getting married. In Vegas. And What they need for it. Including a ring talk. But the don't talk about the ring that Lindsey had. They don't talk about what happened in S5 at all. It's like S5 never existed. Other than right as he's sending his text to Haley Lucas says something like "I know I've been rather dark lately. I'm okay don't worry. Responsible. Sent." The words might be a little off but that's the gist basically. Credit: BrucasplusNaley

-Peyton and Lucas will not get married in Las Vegas because it is not romantic enough or a dream come true to Lucas so instead they get a rental car because Peyton as a mental picture that takes them to Los Angeles and the same hotel room as the first proposal happened in.

When in the room Peyton will tell him the same thing as she told him in the finale about her dream. She’s going to be seated in the same chair as the first time and she'll scream ‘yes, yes’ before he even has the chance to propose again which he will mention but then they will start making out.
